UNITED STATES PATENT OFFICE.

WILLIAM HARRISON MOKINLEY, OF SHANNONDALE, PENNSYLVANIA, AS- SIGN OR OF TWO-THIRDS TO CHARLES H. SONGER AND JOHN A. KURTZ,

BOTH OF SAME PLACE.

AUTOMATIC SWITCH.

SPECIFICATION forming part of Letters Patent No; 318,011, dated May 19, 1885.

Application filed January 21, 1885.

T at whom it may concern:

Be it known that I, WILLIAM H. McKin- LEY, of Shannondale, in the county of Clarion and State of Pennsylvania, have invented certain new and useful Improvements in Railroad Tracks and Switches; and I do hereby declare that the following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of rail- I 5 way-rail switches which are adapted to be operated by a projection upon the engine or car; and the features of novelty consist, essentially, in the details of construction and general arrangement of parts, all as will be hereinafter fully described, and specifically designated in the claim.

- In the accompanying drawings, Figure 1 represents a top plan view of my improvements; Fig. 2, a longitudinal section thereof 2 5 and Figs. 3 and 4 detail sectional views.

Similar letters of reference occurring on the Several figures indicate like parts.

' Referring to the drawings, A A represent the main track or rails, and B my improved o switch, the two side rails, O O, of which are hinged or pivoted at one end to the blocks a, while the opposite ends have a free lateral motion. These rails G O gradually slope from their free ends, where they come into 5 juxtaposition with the main rails, upward to the blocks a at their pivoted ends, the rail 0 being provided with a central groove or channel, b, its entire length to receive the flanges of the car-wheels, while the opposite 4o rail, G,has a curved or cam-shaped end,C ,with

which a suitable projecting arm upon the engine or cars is adapted to engage to draw the free ends of said rails into position with the main rails, to switch the cars off upon a side Each of the rails O O has an inclined orinwardly-sloping bottom adapted to move uponaseriesofcorrespondingly-shapedblocks,

0, arranged upon the cross-ties D, as shown.

Recessed projections or lugs E depend downward from the bottoms of the rails O O,

to receive the ends of the rods or bars F, which hold or connect the said rails together at suitable distances apart.

(No model.)

H, secured to the ends D of the extended to cross-ties D, and rods I connecting said bar or frame with the lugs E upon the bottom of the rail 0, a suitable hand-lever,K, pivoted within a recessed upright projection, e, being connected by a suitable rod, J, to the lever or frame G.

Between the rail 0 and the said frame G is provided a coiled spring,L,one end of which is detachably secured to the cross-frame G, and the opposite end to a lug or block, f, pivoted within a recessed projection, upon the crosstie D, the object of said spring being to force the rails O O outward and keep the main track open until the switch is drawn in by the projection upon the engine or by the handlever.

In the operation of my invention the projecting arm upon the engine is thrown out to engage the cam-shaped end (3 of the rail 0 when it is desired to leave the main track, thereby drawing both rails G G into juxtaposition with the rails of the main track, and allowing the wheels of the engine and cars to pass off from the main track upon the switchrails O G. The said rails having a gradual slope upward to the side track causes the wheels of the cars to easily and gradually leave the main track and pass on the rails of the switch without jar or displacement of parts.

Having thus described my invention,I claim as new and useful The herein-described railroadswitch, consisting of the side rails, G 0, one of which is provided with the cam-shaped end 0 said rails being pivoted at one end to the blocks a, and connected together at a suitable distance apart by means of the rods F, pivoted within the recessed projections E, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

WILLIAM HARRISON MOKINLEY. Witnesses:
